This summer I went to cut up a fallen tree with my chainsaw. I didn't realize there was pressure built up in the gas can, it wasn't bulging or anything obvious and the thought never even crossed my mind. As I was preparing the saw out in the yard, I pressed the handy dandy button on the gas can spigot and my entire face, eyes and all got covered with gas as the built up pressure was expelled it from the can. I literally could not open my eyes and they burned like they were on fire. I had to crawl on the ground 50 feet or so, blinded and feeling my way, to get to my hose and turn on the water to flush my eyes.
These cans are BS. And as Carnac stated, even on a good day you spill more than you used to.
Government over regulation at its finest.
